Firstly, you've been hiking for 11 years but how much of that experience has been with scrambles? I would not recommend Crib Goch to a novice scrambler. But if you've done a few Grade Ones you should be ok.
Having said that you'll need a good head for heights. Much of the ridge is very exposed (not in the sense of being open to the weather but in the sense of having steep slopes or near-vertical drops immediately below the path). So although the route is mostly straightforward there are quite a few places where a slip or stumble could be fatal.
Here is some useful info from the British Mountaineering Council, including a video of the ridge.

The usual route is to follow the Pyg track to Bwlch Y Moch where you fork right to follow the steep path up to the ridge. From the far end of the ridge you follow well-trodden walkers' paths to the summit of Snowdon. For the return to Pen Y Pass follow the Pyg track or the Miner's track.
If the weather is not good enough to risk Crib Goch, you can walk a circular route from Pen Y Pass to the summit of Snowdon by going up the Pyg track and down the Miner's.
Your date of June 2 is a Wednesday so hopefully it won't be as busy as a weekend. It can be very crowded up there which causes frustration and delay. I'd advise getting to Pen Y Pass as early as you reasonably can - that way you stand a better chance of getting a parking space, you maximise the daylight hours, and - importantly - steal a march on the crowds.
As to timing, that depends on your fitness, pace, the weather, and how crowded it is on the day. The usual estimate from Pen Y Pass to Snowdon summit is roughly 4-6 hours. But if you are fit and experienced you'll probably do the whole walk in under six hours.
IMO Crib Goch is one of the best ridge walks south of the Highlands. Not done the route for four years but hope to do it again this year. Anyway, good luck with it - enjoy
